Author(s): F.O. Tawose* and A.S. Bagbe
A study was conducted to evaluate the insecticidal action of four locally available plants namely: Androgaphisp
aniculata, Chromolena odorata, Mucuna pruriens, Daturastram onium in Zanjo Jaji area of Lokoja, Kogi State Nigeria
against cowpea weevil (Casollobruchusm aculatus), maize weevil (Sitophilus zeamais Motsch.) for repellency, adult
mortality and antioviposition and growth inhibition tests. The experiment was carried out in the laboratory of Botany
Department, Federal University Lokoja. Leaves of four samples were harvested, air-dried and reduced to powder
and 250g were measured, soaked in 1litre of distilled water for 48 hours and filtered. A total of forty plates were used
consisting of 10 seeds each with 4 plates per treatments. Results revealed that all test materials exhibited repellency
action against cowpea and maize weevil. Extracts from the leaves o.. Read More»
